The total synthesis of heliconol A, a representative of a new class of polyketide-derived hemiketals containing a reduced furanocyclopentane unit, has been achieved via the stereoselective reduction of a ketone, the face selective dihydroxylation, a Sonogashira coupling reaction, and a cis-selective reduction as the key steps.

The diastereoselective synthesis of the macrolactone core of amphidinolide W was successfully accomplished using Evans{\textquoteright} asymmetric alkylation, Aldol reaction, Julia-Kocienski olefination, and Kita{\textquoteright}s macrocyclization protocol.

A flexible and efficient asymmetric route to the synthesis of a 12-membered macrolactone core and a 6-epi analogue of amphidinolide W has been accomplished from commercially available 4-pentenoic acid. The successful generation of stereocenters was achieved by utilizing an Evans{\textquoteright} chiral auxiliary-based alkylation and aldol reaction. Other key reactions such as a Julia-Kocienski olefination, Kita{\textquoteright}s macrolactonization, ring closing metathesis (RCM) reaction, and Yamaguchi{\textquoteright}s esterification were significant for the construction of the macrolactone cores.
